What caused such gel electrophoresis - explained

To help avoid mistakes when preparing gel electrophoresis, here are some tips to follow:
Careful planning: Plan your gel electrophoresis experiment in advance. Determine the type and concentration of gel you need, the appropriate buffer, and the voltage and run time required for your specific application.
Use clean equipment: Ensure that all equipment, such as gel trays, combs, and pipettes, are clean and free from any residue or contaminants that may interfere with gel formation or sample loading.
Accurate measurements: Precise measurements of agarose, buffer, and other components are crucial. Use calibrated measuring tools, such as analytical balances or graduated cylinders, to ensure accurate quantities.
Proper gel preparation: Follow the instructions for preparing the gel, including the correct ratio of agarose to buffer, appropriate heating and cooling times, and any necessary additives such as DNA stains or ethidium bromide. Make sure the gel is thoroughly mixed to prevent uneven distribution of agarose or buffer.
Combs and well formation: Ensure that the comb is properly inserted into the gel tray and that the combs are level to create straight and well-formed lanes. Apply a small amount of lubricant, such as glycerol, to the comb edges to facilitate easy removal without damaging the gel.
Sample loading: When loading samples into the wells, use a consistent volume and maintain a proper order to avoid confusion or mixing up samples. Be careful not to introduce bubbles during sample loading, as they can affect band resolution.
Electrophoresis conditions: Set up the electrophoresis apparatus correctly, making sure the gel is immersed in the buffer and that the electrodes are properly connected. Use the appropriate voltage and run time based on the size of your DNA fragments and the gel concentration.
Safety precautions: Adhere to proper safety procedures when working with electrophoresis equipment, such as wearing gloves, using appropriate protective barriers, and handling ethidium bromide or other DNA stains according to safety guidelines.
Documentation: Record the details of your gel preparation, including the concentrations, voltages, and run times used, as well as the samples loaded and any other relevant information. This will help you keep track of your experiments and troubleshoot any issues that may arise.
By following these guidelines and paying attention to detail, you can minimize errors and ensure reliable results when preparing gel electrophoresis.

What do you mean by above leakage ?

[@GeneticsLessons]

I do not understand your question.

[@Holy_Randomness]

He means sample escaping from the top the of the well as a result of overloading. Always fill less than two-thirds of the well with your sample to prevent any potential spillage out of the well.
